Abstract
Description
- This invention relates to adjustable motor vehicle steering columns.
- In common tilt-adjustable motor vehicle steering columns, the vertical position of a steering wheel relative to a driver seated in the vehicle is adjusted by pivoting a tilt-housing on which the steering wheel is rotatably supported up and down about a lateral centerline. A lock shoe on one of a stationary mast jacket of the steering column and the tilt-housing has a plurality of notches which seat on a pin on the other in discrete vertical positions of the steering wheel. A positive attribute of this construction is that it successfully resists angular displacement of the tilt-housing even when substantial forces are applied to the steering wheel urging upward pivotal movement of the tilt-housing. A less positive attribute of this construction is that it provides only as many adjusted positions of the steering wheel as there are notches in the lock shoe. Other tilt-adjustable motor vehicle steering columns have been proposed in which infinite adjustability is achieved by a clamp which induces friction between moveable and stationary elements of the steering column. Practical embodiments of such friction clamps, however, do not match the positive retention performance of the aforesaid lock shoe construction when the tilt-housing is forced upward.
- This invention is a new and improved adjustable motor vehicle steering column having a stationary mast jacket, a tilt-housing supported on the stationary mast jacket for up and down pivotal movement, a steering wheel rotatably supported on the tilt-housing, a friction clamp for infinite tilt adjustment, and a wedge lock to prevent upward pivotal movement of the tilt-housing in the event the friction clamp is overpowered. The friction clamp has inner and outer jaw elements which clamp together relatively moveable surfaces on the stationary mast jacket and on the tilt-housing when an operating lever is pivoted from an unlocked position to a locked position. The wedge lock includes an arc-shaped land on the tilt-housing, a locking ring having an eccentric outer edge rotatably supported on the stationary mast jacket concentric with the arc-shaped land, and a torsion spring biasing the locking ring toward engagement of the eccentric outer edge thereof on the arc-shaped land. If the friction clamp is overpowered, the arc-shaped land effects rotation of the locking ring to a wedged position against the land at the onset of pivotal movement of the tilt-housing in which further pivotal movement of the tilt-housing is foreclosed. The operating lever forcibly rotates the locking ring in a direction separating its eccentric outer edge from the arc-shaped land when the friction clamp is open and releases the locking ring when the friction clamp is closed.

- An adjustable motor
vehicle steering column 10 according to this invention includes atubular mast jacket 12 and a tilt-housing 14. Ayoke 16 having a pair ofintegral bosses 18A-B is rigidly attached to themast jacket 12. A pair ofpivot pins 20A-B on respective ones of a pair ofsidewalls 22A-B of the tilt-housing 14 engage journals, not shown, on thebosses 18A-B whereby the tilt-housing is supported on the mast jacket for up and down pivotal movement about a firstlateral centerline 24 of the steering column. A steering wheel, not shown, is supported on the tilt-housing for rotation about alongitudinal centerline 26 of the tilt-housing. The vertical position of the steering wheel relative to an operator seated in a passenger compartment of the motor vehicle is adjusted by up and down pivotal movement of the tilt-housing. - A
friction clamp 28 between the tilt-housing 14 and theyoke 16 includes ashaft 30, anoperating lever 32, andcam 34. Theshaft 30 is supported on thebosses 18A-B in alignment with a secondlateral centerline 36 of the steering column and traverses thesidewalls 22A-B of the tilt-housing 14 through respective ones of a pair ofarcuate slots 38A-B in the sidewalls the centers of curvature of which coincide with the firstlateral centerline 24. - A thrust washer 40 on the
shaft 30 is disposed between abolt head 42 at one end of the shaft and thesidewall 22B of the tilt-housing. The other end of theshaft 30 is received in abore 44 in the operating lever whereby the operating lever is supported on theyoke 16 for pivotal movement about the secondlateral centerline 36 between a locked position, Figure 2, and an unlocked position, not shown, about 45°-90° clockwise from the locked position. Anut 46 retains the operating lever on theshaft 30. - The
cam 34 is rotatably supported on theshaft 30 between thesidewall 22A of the tilt-housing and the operating lever and includes an outercylindrical wall 48, aflat side 50 facing thesidewall 22A of the tilt-housing, and alug 52 on the flat side. The lug projects into thearcuate slot 38A and cooperates with theshaft 30 in preventing rotation of thecam 34 relative to theyoke 16 about the secondlateral centerline 36 without interfering with up and down pivotal movement of the tilt-housing. - The
cam 34 has a plurality ofarcuate ramps 54 on the side thereof opposite theflat side 50. Each of the ramps extends between alower platform 56 and anupper platform 58. Theoperating lever 32 has a plurality offollowers 60 thereon corresponding to the number oframps 54 on the cam. Thefollowers 60 bear against the cam and traverse theramps 54 between the upper and lower platforms concurrent with pivotal movement of the operating lever between its locked and unlocked positions. Theflat side 50 of the cam and thethrust washer 40 define a pair of outer jaw elements of the friction clamp outside of thesidewalls 22A-B of the tilt-housing 14. Thebosses 18A-B define a pair of inner jaw elements of the friction clamp inside of thesidewalls 22A-B. - In the unlocked position of the
operating lever 32, not shown, thecam followers 60 seat on thelower platforms 56 and the friction clamp is open, i.e. separation between the inner and outer jaw elements of the clamp is maximum and the tilt-housing 14 is freely pivotable up and down about the first lateral centerline. When theoperating lever 32 is pivoted from its unlocked position to its locked position, Figures 2-3, thecam followers 60 traverse theramps 54 from thelower platforms 56 to theupper platforms 58 and the friction clamp is closed, i.e. separation between the inner and outer jaw elements is minimum and thesidewalls 22A-B of the tilt-housing are squeezed against thebosses 18A-B, respectively. Friction thus induced between the sidewalls and the bosses immobilizes the tilt-housing relative to the stationary mast jacket in any position of the tilt-housing. - A
wedge lock 62 includes an arc-shaped land 64 on the tilt-housing 14 at the bottom of thesidewall 22A concentric with thearcuate slot 38A and anannular locking ring 66 supported on the outercylindrical wall 48 of thecam 34 for rotation about the secondlateral centerline 36. Thelocking ring 66 has an eccentricouter edge 68 the radius of which from the center of the ring varies from a maximum R1 to a minimum R2, Figure 4. The eccentricouter edge 68 is interrupted by anotch 70 having afirst shoulder 72 at one end and asecond shoulder 74 at the other end. - A
coil torsion spring 76 is disposed around theshaft 30 between theoperating lever 32 and thecam 34 and includes a first hookedend 78 projecting into a socket in the locking ring and a second hookedend 80 projecting into a socket in the operating lever. Thetorsion spring 76 biases the locking ring counterclockwise, Figures 1-2. Arigid tang 82 on the operating lever outside of thetorsion spring 76 extends into thenotch 70 between theshoulders - In the locked position of the
operating lever 32, Figure 2, therigid tang 82 is about midway between the first andsecond shoulders notch 70 and thetorsion spring 76 rotates the locking ring counterclockwise, Figure 2, until the eccentricouter edge 68 thereof seats against the arc-shaped land 64. In that circumstance, if the tilt-housing 14 experiences an upward force of sufficient magnitude to overpower thefriction clamp 28, the arc-shaped land 64 rotates thelocking ring 66 toward a wedged position between thecam 34 and the land concurrently with the onset of upward pivotal movement of the tilt-housing 14. In its wedged position, thelocking ring 66 induces substantial friction between the locking ring and each of thecam 34 and the arc-shaped land 64 which effectively immobilizes the tilt-housing 14 and prevents further upward pivotal movement of the latter. In an alternate embodiment, not shown, the eccentricouter edge 68 and the arc-shaped land 64 may have meshing teeth or serrations thereon to positively rotate the locking ring to its wedged position. - When the
operating lever 32 is pivoted clockwise, Figure 2, from its locked position to its unlocked position, the friction clamp transitions from closed to open. Concurrently, therigid tang 82 on theoperating lever 32 engages thesecond shoulder 74 ofnotch 70 after a few degrees of pivotal movement of the operating lever and forcibly rotates thelocking ring 66 clockwise to separate the eccentricouter edge 68 of the locking ring from the arc-shaped land 64. With the eccentric outer edge separated from the arc-shaped land, the wedge lock is immobilized and the tilt-housing 14 is freely pivotable up and down. When a comfortable position of the steering wheel is achieved, the control lever is pivoted from its unlocked position to its locked position to concurrently close the friction clamp and reestablish engagement of the eccentricouter edge 68 of the locking ring on the arc-shaped land 64.
